Oracle COM Automation Feature, PL/SQL Errors

The following is a list of Oracle COM Automation Feature PL/SQL errors and their common causes.

COM-0001: Not a Boolean type: Cause: The property type, or return value type, is not a boolean, but a Boolean value was requested.; Action: Make sure that the variable is of the appropriate data type.

COM-0002: Invalid Token or no interface for token: Cause: The token that was specified does not reference any COM object created using CreateObject, or the COM object was freed using DestroyObject.; Action: Make sure that the interface exists.

COM-0003: Maximum Objects reached: Cause: Only 1024 COM objects can be active at any time. This includes COM objects created using CreateObject as well as COM objects obtained as property values and return values.; Action: Make sure that objects are destroyed after they are used, by calling DestroyObject.

COM-0004: The registered CLSID for the ProgID is invalid: Cause: The ProgID is located in the registry, but the CLSID associated with the ProgID is not correct.; Action: Check that the COM component of the specified ProgID is registered.

COM-0005: An error occurred writing the CLSID to the registry: Cause: The ProgID is not located in the registry. An attempt was made to create the ProgID and assign a CLSID to it, but the registry could not be modified.; Action: Make sure your registry can be written to and is not corrupted.

COM-0006: A specified class is not registered in the registration database: Cause: A specified class is not registered in the registration database.; Action: Make sure that the class is registered.

COM-0007: Failed to initialize COM Automation object: Cause: There was an error creating the COM object.; Action: Make sure that the object is registered as a COM Automation object.

COM-0008: No interface is supported: Cause: This COM object does not support the IDispatch interface, so it cannot support COM Automation.; Action: Verify that the interface specified is valid.

COM-0014: Failure to invoke: Cause: There was an error invoking the method or property.; Action: Verify that the method name is valid for the object.

COM-0015: Bad parameter count: Cause: The number of parameters given for the method or property is different from the number of parameters expected.; Action: Make sure that the number of parameters for a method is equal to the count.

COM-0017: The application needs to raise an exception. The structure passed in pexcepinfo should be filled in: Cause: The COM object threw an exception.; Action: The exception includes an error source, error description, help file, and the help file context. Call GetLastError to get this additional information

COM-0018: The requested member does not exist, or the call to Invoke tried to set the value of a read-only property: Cause: The requested member does not exist, or the call to Invoke tried to set the value of a read-only property.; Action: Make sure that the property value can be written to or the member exists.

COM-0020: One of the arguments in rgvarg could not be coerced to the specified type: Cause: One of the arguments is not the type expected by the method or property, and the argument cannot be coerced to the expected type.; Action: Make sure that the coerced arguments are of compatible datatypes.

COM-0022: One or more of the arguments could not be coerced: Cause: One of the arguments is not the type expected by the method or property, and the argument cannot be coerced to the expected type.; Action: Make sure that your arguments are compatible.

COM-0025: Not an optional parameter: Cause: A required argument is missing.; Action: Make sure that your argument count is correct for the number of -parameters passed in.

COM-0026: Name exceeded the maximum character allowed: Cause: The property name, method name, server name, or ProgID is too long.; Action: Enter less than 1024 characters for the name.

The following is a list of Microsoft COM Automation errors and their common causes. Both the hexadecimal and binary error codes are listed.

(0x800401f3) (-2147221005) Invalid class string: Cause: The specified ProgID or CLSID is not registered as a COM object in the registry of the local computer.; Action: Correctly install the COM component.

(0x8007007e) (-2147024770) The specified module could not be found: Cause: The specified COM object is registered as an in-process COM server (DLL file), but the DLL file could not be found or loaded.; Action: Correctly install the COM component.

(0x80020004) (-2147352572) Parameter not found: Cause: A named parameter was specified before a positional parameter.; Action: Ensure that all named parameters are specified after all positional parameters.

(0x80020005) (-2147352571) Type mismatch: Cause: The data type of a PL/SQL local variable used to store a returned property value or a method return value did not match the Visual Basic data type of the property or method return value, or the return value of a method was requested, but it does not return a value.; Action: Ensure that the local variable is of the appropriate data type and, for methods, make sure the return value is not type void.

(0x80020006) (-2147352570) Unknown name: Cause: The specified property or method name was not found for the specified object.; Action: Verify that the method or property name is valid for the object.

(0x80020008) (-2147352568) Bad variable type: Cause: The datatype of a PL/SQL or Java value passed as a method parameter did not match the COM Automation data type of the method parameter, or a NULL value was passed as a method parameter.; Action: Ensure that any local variables used as method parameters are of the appropriate data type and are set to a value other than NULL.

(0x80080005) (-2146959355) Server execution failed: Cause: The specified COM object is registered as a local COM server (.EXE file), but the .EXE file could not be found or started.; Action: Correctly install the COM component.
